PROBLEM TO BE SOLVED: To provide a substrate body for a photocatalyst having high photocatalytic activity and excellent fixing property to the substrate, capable of being applied to both of gas and an aqueous solution, having excellent separation/workability with a liquid to be treated such as contaminated water or the like when it is particularly applied to the aqueous solution and having sufficient strength capable of being borne for a practical use; the photocatalyst body using the substrate; and a device and a method for preventing an environment pollution utilizing the photocatalyst body. SOLUTION: The photocatalyst particle is fixed onto a surface of a granulation type artificial light weighted aggregate covered with a glass based shell making an inorganic substance as a binder. |
